HMA-2 & HMA-2A Series
Direct-Fired Make-Up Air Burner
Technology in Direct-Fired Gas Burners
Our innovative two stage combustion burner is not just a modification or improvement to our original HMA product line, but a completely new approach to direct-fired combustion. The two-stage combustion improves control of the flame process, meets and exceeds the ANSI Standards and outperforms the competition. By having two separate flames within the burner combustion zone, the flame is more stable, shorter and cleaner. Two stage combustion reduces emissions allowing for higher temperature rise, wider operation range, easy installation, and simple profile opening.
Technology for Direct-Fired Applications Plus Flexibility in Configuration
Straight, elbow, tee and back inlet sections easily configure to desired capacity maximizing efficiency for installation and performance. Burners may be ignited by proven pilot or direct spark. Pilots are available for flame rectification or ultraviolet detection. Contact the factory for specifications.
Reduced NO2 and CO Emissions
Lower emissions levels that easily pass the ANSI Z83.4, Z83.18 and Z83.25 standards.
Up to 750,000 BTU’S per foot. (Higher BTU levels can be achieved if ANSI Z83 Standards or CO and NO2 emissions are not of a concern. Process heaters can fire up to 1,000,000 BTU’S a foot or more.)
Increased Differential Pressure Drop & Higher Velocities
HMA-2A burners can operate between 0.05″ to 1.4″ W.C. differential pressure range or in air velocity between 800 fpm to 4000 fpm.
Reduced Inventory & Shipping Costs
Single burner casting can be fired with natural, propane or butane gas, reducing burner inventory. (Consult factory for applications using butane fuels).
30-1 turndown can easily be achieved with proper modulation control and for modular gas valves.
